Anthropic said on Monday it has confidentially filed for a US initial public offering, positioning the artificial intelligence company for what could become one of the most closely watched listings in the technology sector.
The company behind the AI model Claude noted that the number of shares to be offered and pricing have not yet been determined, and that timing will depend on market conditions and other factors. No further details on valuation or listing size were disclosed.
Anthropic last raised capital in late May, securing $65 billion in a Series H financing round at a reported post-money valuation of $965 billion.
Wedbush analysts wrote in a note that the filing marks a “major step” for Anthropic as it positions itself ahead of competitors in the race to public markets. The firm said the move could help Anthropic get ahead of OpenAI, which it expects may also pursue a confidential filing process, and comes as multiple high-profile technology companies prepare for potential IPO activity.
The analysts pointed to what they described as an emerging “race” among large private companies, including Anthropic, OpenAI and SpaceX, to access public markets over the coming months, suggesting this could signal a broader reopening of the IPO window after a relatively subdued period.
“We believe this represents an opening of the floodgates for the IPO market, which has been relatively dormant for a few years, with these three major conglomerates set to go public later this year, but this has turned into a race to reach public markets over the coming months,” Wedbush wrote.
“Investors will be eagerly awaiting more details from Anthropic’s S-1 over the coming weeks.”
Wedbush also highlighted recent corporate developments, including Anthropic’s reported growth in annual revenue run-rate and ongoing expansion of its compute infrastructure through partnerships with major cloud and semiconductor providers.
The analysts noted recent updates to Anthropic’s Claude model family, including improvements in performance, cost efficiency and reliability, as well as expanded capacity commitments intended to support rising demand.
